AMD has banned the use of Power Play Table (PPTable) in the Windows registry on its Radeon RX 7000 graphics cards.This limits the overclocking capabilities of the graphics cards and, in particular, prevents fine-tuning GPU power and frequency curves outside of their official specifications.This has been pointed out by well-known enthusiast Buildzoid.Image source: AMDThe Power Play tables are an alternative method of changing GPU clock frequency, power and voltage via the Windows registry instead of modifying or replacing the BIOS.At the same time, it is the safest method of running GPUs outside of their official specifications, as it prevents any risk that may arise from BIOS re-flashing.Setting up Power Play tables or changing the BIOS has several advantages over traditional AMD overclocking methods and features offered by Radeon Software Adrenalin.First, users can bypass GPU hardware limitations associated with the firmware and overclock the graphics card as much as possible.Secondly, Power Play tables allow for fine-tuning of the voltage/frequency curve to improve the power efficiency of the graphics card.In other words, this method allows you to fine tune the video card's GPU behavior in more detail, which is not possible with AMD's usual overclocking software.Last generation Radeon RX 6000 video cards do not have the ability to fine tune power via Power Play tables blocked.Why AMD decided to prohibit access to it on Radeon RX 7000 video cards is unknown.However, one AMD engineer on the Reddit forum in a thread discussing power consumption issues with Radeon RX 7000 graphics cards reported that \"architecturally RDNA3 has some changes in how to manipulate the power tables.\"
AMD called Radeon RX 7900 XTX a competitor to GeForce RTX 4080, and announced FSR 3.0 compatibility with older graphics cards
PCWorld reporters managed to talk to Frank Azor, AMD chief gaming and marketing architect, and get some details about the Radeon RX 7000 graphics cards on the new RDNA 3 architecture.AMD's representative said why at the time of the presentation of graphics cards Radeon RX 7900 XTX and RX 7900 XT novelties were not compared to models NVIDIA GeForce RTX 40-series.Image source: VideoCardzAccording to Mr.Azor, AMD is positioning flagship gas pedal Radeon RX 7900 XTX as a competitor to the GeForce RTX 4080.Since NVIDIA has not yet released the card, AMD had no information about the performance of the gas pedal to add to its comparison charts.\"[The Radeon RX 7900 XTX] is designed to compete with the RTX 4080.We have no information about its performance.This is the main reason why you didn't see any comparisons with NVIDIA solutions \u003C...> the $999 card can't be a competitor to the RTX 4090, which is rated 60% more expensive.[The Radeon RX 7900 XTX's] competitor is the RTX 4080,\" Azor said.He also commented on the announcement of FSR 3.0 image scaling technology and noted that the decision to introduce a new version of FSR was not spontaneous.According to him, FSR 3.0 will not only be supported by RDNA 3-based graphics cards.\"Our decision to announce FSR 3.0 is not some kind of backlash or a desire to quickly introduce a competitor to NVIDIA DLSS 3.We have been developing this technology for some time.Why will it be available later than many would expect? The main thing is to remember the key philosophy behind FSR technology.After all, FSR 1.0 and FSR 2.0 do not only work on RDNA and RDNA 2 graphics cards.They are supported by other generations of AMD graphics gas pedals.They are also supported by our competitors' graphics cards.This is much more difficult to implement than if we just added FSR 3.0 support only for RDNA 3 graphics cards.We really want FSR 3.0 to work on other graphics cards as well,\" Azor commented.Hinting at DLSS 3, which is only supported by GeForce RTX 40-series gas pedals, Azor added that support for just one architecture is much easier to implement.However, AMD has made a promise that FSR will be supported by multiple graphics architectures.But it takes time to implement this.The company is not yet sure it can 100% keep that promise, but it will \"try very hard.\"
AMD introduced the Radeon RX 7900 XT and RX 7900 XTX graphics cards - the older one is priced at $999
AMD introduced its flagship gaming graphics cards Radeon RX 7900 XT and Radeon RX 7900 XTX.
New products are based on flagship graphics processor with RDNA 3 architecture, which AMD calls the world's first GPU with a chiplet design - it consists of several crystals.
AMD's new flagship RDNA 3 architecture GPU includes 58 billion transistors, and their density has increased by 165% compared to previous-generation (RDNA 2) GPUs.
The big crystal in the center is made by 5-nm process technology and has an area of 300 mm2.It is called GCD (Graphics Compute Die) and includes all GPU computing blocks, as well as other necessary elements. Next to it are six small crystals with high speed memory Infinity Cache.
They are 6nm processors, have an area of 37mm2 each and are called MCD (Memory Cache Die).The bus bandwidth between GCD and MCD is 5.3 Tbytes/sec.
Note that Radeon RX 6000 had Infinity Cache memory on the same chip as GPU, but had 2.7 times less bandwidth. The new chips have a theoretical peak performance of 61 Tflops in single precision floating point operations (FP32), 2.7 times higher than the previous generation GPUs could offer (23 Tflops).
AMD notes that it optimized its computing block architecture for gaming, dramatically increasing performance.It also doubled the number of instructions executed per clock cycle, and increased the processing speed of ray tracing operations (by 50% for each processing unit) and artificial intelligence (by 2.7 times).
According to AMD, the new flagship Radeon RX 7900 XTX is 1.5-1.7 times faster in games than the Radeon RX 6950 XT.And when using ray tracing, which was not the strongest point of the last generation graphics cards, the performance increased by 1.5-1.6 times.
In general, AMD positions the new graphics card as a solution for 4K gameplay with high frame rate.And to achieve even higher frequency will help to scale FSR.Unfortunately, AMD did not compare its novelties with its competitors. Senior Radeon RX 7900 XTX has got graphics processor with 96 compute units (Compute Units, CU) with RDNA 3 architecture, which means there are 12,288 stream processors.
The chip runs at a clock speed of 2.3 GHz, which is the average frequency in games.Next to it is 96 MB of high-speed Infinity Cache memory, and the amount of GDDR6 video memory is 24 GB.It is connected via a 384-bit bus.
The graphics card power consumption is 355W. The subflagship Radeon RX 7900 XT has a graphics processor with 84 CU, which carry 10,752 stream processors.The average gaming frequency is claimed to be 2 GHz.The card has 80 MB of Infinity Cache memory, and the amount of GDDR6 video memory is 20 GB, and it is connected via a 320-bit bus.The consumption level of the card is 300 W.
The new AMD reference graphics cards have a cooling system with three fans and take up 2.5 expansion slots in height.
For additional power each has two 8-pin connectors.AMD separately pointed out that \"its new graphics cards won't need new chassis or new power supplies.\" This was obviously a kick in the teeth for NVIDIA, whose flagship GeForce RTX 4090 turned out to be huge, and also uses new 12+4 pin power connector. Also AMD emphasized on the new graphics cards support of the latest DisplayPort 2.1 interface.
It provides the ability to output images in 8K resolution at up to 165 Hz or in 4K resolution at 480 Hz.The problem so far is that there are no monitors with this interface and these characteristics on the market.Here we should also note the support of hardware acceleration when working with AV1 codec.
The recommended price of AMD Radeon RX 7900 XTX video card will be $999, while the junior Radeon RX 7900 XT is priced at $899.Both graphics cards will go on sale on December 13.
Recall that the GeForce RTX 4090 is priced at $1599, while the GeForce RTX 4080 will cost from $1199.
AMD announced FSR 3.0 technology and HYPR-RX feature - both will boost FPS, but will not appear until 2023
As part of the presentation of the next generation flagship graphics cards Radeon RX 7900 XTX and RX 7900 XT AMD also announced two new software technologies that will be part of the Radeon Software Adrenalin graphics driver in the foreseeable future.
We're talking about a new version of FidelityFX Super Resolution 3.0 image scaling technology, as well as AMD's new HYPR-RX feature.Amd Vice President Scott Herkelman said while speaking at the event that FidelityFX Super Resolution 3.0 (FRS 3.0) will get support for the Unreal Engine 5 game engine.
He also stated that FSR 3.0 will provide twice the gaming performance of FSR 2.0.Unfortunately, he did not share more details about FSR 3.0, but indicated that the technology will become available next year.
The Radeon Software Adrenalin graphics driver will also include the new AMD HYPR-RX feature.
It will allow with the click of a button to reduce gaming latency, enable FSR scaling technology, and activate the Radeon Boost feature to improve gaming performance.
According to an AMD spokesperson, in Dying Light 2, which was cited as an example, activating the AMD HYPR-RX feature allows for an 85% increase in gaming performance and a 1/3 reduction in latency.
AMD HYPR-RX will be a kind of combined response to NVIDIA Reflex and NVIDIA DLSS technologies.According to the company, the feature will appear as part of the Radeon graphics driver in the first half of 2023.
ASUS announced Radeon RX 7900 XTX and RX 7900 XT in TUF Gaming version
ASUS announced graphics cards Radeon RX 7900 XTX and RX 7900 XT in their own version TUF Gaming.The company is not ready to share the specs of new products, but the manufacturer has revealed some details about them.Image source: ASUSBoth gas pedals will get a massive cooling system, equipped with three fans.The thickness of video cards will be three expansion slots.Both will get a dual BIOS system with quiet and performance modes. Unlike the reference versions Radeon RX 7900 XTX and RX 7900 XT, variants from ASUS have got not two, but three 8-pin connectors of additional power.In addition, new items will be the first gaming cards from ASUS, which will support DisplayPort 2.1 interface. Graphics card Radeon RX 7900 XTX has a graphics processor with 12,288 stream processors, the reference gaming frequency is 2.3 GHz.The card has 24 GB of GDDR6 memory with 384-bit bus support.The Radeon RX 7900 XT model is based on a GPU with 10,752 cores and has a reference frequency of 2 GHz.This gas pedal has received 20 GB of memory GDDR6 with support for 320-bit bus.ASUS has not reported with what frequencies will run GPUs in its video cards.Also unknown is the price of announced Radeon RX 7900 XTX and RX 7900 XT TUF Gaming models.However, most of the prices for these graphics cards are close to the recommended ones, which are $999 and $899 respectively.The company only confirmed that the novelties will be on sale in December this year.
AMD Navi 31 flagship multi-chip GPU showed up in photos ahead of the announcement
A photo of AMD Navi 31 GPU based on RDNA 3 architecture, which will form the basis of higher-end Radeon RX 7000 graphics cards appeared at Angstronomics' disposal.Recall that the official announcement of the latter will be held this evening.Image source: AMDThe presented photo of Navi 31 GPU confirms the use of chiplet design.In the photo you can note the main graphics chip Graphics Chiplet Die (GCD) in the center and six auxiliary crystals Memory Chiplet Dies (MCD).Image source: AngstronomicsThe same source previously reported the alleged specifications of the Navi 31 GPU.So, the main GCD chip with an area of about 308 mm2 contains 48 WGP (Workgroup Processors) blocks.Each WGP has two Compute Units (CUs).Thus, the total number of CUs in the chip is 96.And the total number of Arithmetic Logic Units (ALUs or Area Stream Processors) within the 96 CU's would be equal to 12,288 units.The area of one MCD chip, in turn, is about 37.5 mm2.The total area of the GCD with all the MCD chips is approximately 533 mm2.The area of the entire GPU package is 2612 mm2 (dimensions 55 × 47.5 mm).Each MCD contains 16 Mbytes of AMD Infinity Cache.Thus, Navi 31 GPU will get 96 MB of Infinity Cache, which is less than the same Navi 21 (128 MB) that powers Radeon RX 6900 XT/6950 XT.It is also reported that Navi 31 GPU supports 384-bit memory bus with up to 24 GB of GDDR6 memory at 20 Gbit/s per pin.This chip is expected to be the core of the Radeon RX 7900 XTX graphics gas pedal. Expected specifications of AMD Navi 31, Navi 32 and Navi 33 graphics processors.Image source: VideoCardzIt is expected that during today's presentation AMD will present only the senior models of Radeon RX 7000 gas pedals based on Navi 31.Models based on Navi 32 and Navi 33 GPUs will probably be announced later.However, we will be able to find out the exact information in a few hours.
AMD to unveil Radeon RX 7000 graphics cards tonight
AMD will unveil Radeon RX 7000 graphics cards on the latest RDNA 3 architecture graphics processors tonight.The start of the presentation, entitled Together we advance_gaming is scheduled for 23:00 Moscow time.The presentation will be available for all those who wish to watch it on AMD official YouTube channel.AMD itself describes the upcoming event as follows: \"AMD executives will detail AMD's new high-performance and energy-efficient AMD RDNA 3 architecture, which will deliver a new level of performance, efficiency and functionality for gamers and content creators.\"At the moment, very little is reliably known about the upcoming new products.AMD showed the graphics chip Navi 3X back in August and already then it was known that the RDNA 3-based GPU will consist of several chips, by analogy with AMD CPUs.This should reduce the cost, which would have a positive effect on the price of graphics cards.At least, that should be so in theory.Crystals GPU, or at least some of them will be made at 5nm process on the production facilities TSMC.Also earlier head of AMD Lisa Su (Lisa Su) said that the next generation graphics will provide 50% higher performance per watt of energy compared to current solutions, meaning Radeon RX 6000 on the RDNA 2 architecture.Also AMD representatives said recently that they will not be getting a new (and potentially problematic) power connector with 12+4 pins.The latter is confirmed by recently leaked photo which seems to depict Radeon RX 7900 XT reference graphics card - it has a pair of 8-pin connectors.Novelty is larger than the current flagship in the face of Radeon RX 6900 XT, but still not as huge as GeForce RTX 4090 graphics cards.Note that AMD is rumored to be preparing several graphics cards on the flagship GPU next generation: Radeon RX 7900 XT and Radeon RX 7900 XTX.They are rumored to offer up to 24 GB of GDDR6 memory and up to 12,288 stream processors.Whether this is true we will find out in a few hours.
Radeon RX 7900 in reference version showed up in photos - card has two 8-pin power connectors
One of Twitter users shared photos of reference version of AMD Radeon RX 7900 graphics gas pedal.According to him, the pictures were published in one of the closed communities for enthusiasts.\t\t\t\t\t\t\t\tImage source: Twitter / @9550pro The photo does not show the final version of the graphics gas pedal, but only an engineering sample.Such a conclusion can be made at least from the fact that the card uses a red PCB, on which in some places you can see contact points for voltage monitoring.However, the gas pedal cooling system is very similar to the one that the final version will receive.Its outlines could be seen back at the August AMD presentation.In the photos presented Radeon RX 7900 is compared with the reference version Radeon RX 6900 XT.Novelty is longer than its predecessor but has the same set of two 8-pin power connectors as the model on the RDNA 2 architecture.The appearance of cooling system has changed relative to the previous generation graphics cards Radeon.However, these changes are more of a cosmetic nature.\t\t\t\tThe cooling system of the reference version of the new generation AMD video card includes three fans.The source did not specify what gas pedal model on the RDNA 3 architecture has got on the photo.It could be either Radeon 7900 XT, or the flagship Radeon RX 7900 XTX.Below in the table you can see the characteristics that are attributed to these gas pedals.In particular, GPUs of video cards will allegedly get up to 12,288 stream processors, and video cards themselves will be equipped with up to 24 GB of GDDR6 memory.\t\t\t\t\t\t\t\tImage source: VideoCardz Video cards Radeon RX 7000 series will be officially presented on November 3.According to recent rumors, they will go on sale in early December.We expect the announcement of at least two models of gas pedals based on RDNA 3 architecture - the aforementioned Radeon 7900 XT and Radeon RX 7900 XTX based on Navi 31 processors.If you believe the rumors, the older models Radeon RX 7000 will use the GPU with an innovative chip design.
